Storage & Transportation
Proper storage and transportation of Lithium Polymer High Voltage (LiHv) batteries is critical for the safety and longevity of the IB388 and your aircraft. Mishandling of LiHv batteries can lead to reduced battery life, damage to the battery or aircraft, and fire.
Storage
Storage is defined as any period of time where the battery is inactive for more than 48 hours.
Batteries should be stored with an internal voltage between 22.2v to 23.4v, or an individual cell voltage of ~3.8v. By default IB388 batteries will automatically self discharge to this level if initially stored at a higher level for more than 48 hours.
The included IMARS D300 battery charger has a storage function which will charge or discharge your battery to this safe level.
Batteries are to be stored in a cool, dry place away from direct sunlight and moisture. Ideal storage temperatures range from -10℃ - 45℃. Unless batteries are stored for greater than 3 months then batteries should be stored between 23±5℃.
LiHv batteries should be stored in a fireproof container specifically designed for lithium batteries. These containers are designed to limit any fire from spreading, while also allowing any internal moisture to escape.
LiHv batteries should be stored away from other flammable or combustible materials.
IB388 batteries should be charge cycled at least once every 3 months to maintain health. Operators should also check the stored LiPo batteries for any signs of damage, swelling or leakage, and check the internal state of health indicator. Dispose of any damaged batteries as per Section: Battery Disposal.
Transportation
The United States Department of Transportation restricts batteries to no more than 30% of their rated capacity during transportation by air or ground. For the IB388 this means the state of charge LEDs are indicating no more than 3/8th charge and the overall voltage is less than 22.8v (3.8v per cell).
Operators can use the included IMARS D300 battery charger to charge or discharge the battery to a safe level, by using the storage function.
NOTE: Discharging using the D300 can take many hours. The fastest way to discharge an IB388 battery is by flying it in the IF800 Tomcat.
Batteries should be transported in the IB388 transportation case.
If you are unable to ship using the IB388 transportation case package batteries as follows:
Packaging: Use a rigid LiPo fireproof case, place batteries in LiPo bags in a rigid case if a LiPo case is not available.
Isolate: Ensure each battery is isolated and cannot come into contact with other batteries or conductive materials.
Terminals: Cover terminals with electrical tape.
Padding: Place LiPo batteries in a case with ample padding material for cushioning and to prevent batteries from moving within the case.
Ensure the transportation case is marked with the LiPo battery designation UN3480 sticker.
As these are considered large lithium ion batteries (>160Wh). They CANNOT be brought onto commercial passenger airplanes. They must be shipped via GROUND.
Operators can ship via Air with proper Dangerous Goods(DG), Hazmat certification (UN3480). Contact your carrier for certification guidelines, classes, and processes.
